Anti-Vandal Switches

We supply a broad range of Anti Vandal switches to suit a variety of applications.  These include vandal resistant switches with ring or dot illumination.  There is a choice of colours, IP ratings (IP40, IP65 and IP67) and voltages (12VDC, 24VDC or 250VAC).  They are also supplied with internal resistors. Vandal switches are available in stainless steel, brass, nickel plated brass and black PBT with screw or solder tab terminations.  Actuators can be domed, flat or raised.  We offer these push switches with 12mm, 16mm, 19mm, 22mm and 25mm cut-outs.  The switching actions can be momentary or latching. Due to the wide choice of switch options, not all items are held in stock.  However, our lead-times are not extensive; between 4-6 weeks for this range. We can also hold buffer stocks or work to scheduled deliveries. Our robust, high quality anti-vandal switches are built for tough, demanding environments.  So, if you have a particular requirement or would like assistance to find the switch you need, please call us on 01258 456360 or send us an email sales@abcomponents.co.uk

Touch Switches

Capacitive touch switches are a popular design choice for modern applications. They are robust, durable and aesthetically pleasing. Applications include domestic appliances, vending machines, industrial controls, infotainment centers and medical and food products.  Our touch switches are an extension to our anti-vandal switch range and are also known as capacitive vandal resistant switches. Key features for our range:

• Finger touch trigger, even when wearing medical gloves
• Ring illumination
• Internal resistor - no need to connect an external resistor
• Electrical endurance – 50,000,000 cycles
• Durable and waterproof with IP68 rating
• Visually striking switches suitable for a wide variety of applications, particularly where product appearance is key.

Customer requirements for touch switches are frequently specific to individual applications. Therefore, our range offers numerous product variations.   This enables considerable design freedom.  Please note, minimum order quantities will apply, however, these are relatively small. Switch Options:

• Cut-out – 16mm/19mm/22mm
• Latching & Momentary / Normally Open & Normally Closed
• Illumination – Non-illuminated/Single LED/Dual LED
• LED voltage – 5VDC/12VDC/24VDC

For more information on our touch switch range, please call 01258 456360 or email sales@abcomponents.co.uk We will be very happy to discuss the various options with you.

Rocker Switch   

The rocker switch is one of the most common forms of switches. Its name is derived from the see saw action of the rocker - when one side of the switch is pressed, the other side raises. They are used to turn the power on and off devices and applications which are operated by electricity. There are many variations including size, contact form, voltage, illumination, number of poles and throws etc.  We will help to clarify these below:

Poles & Throws

Commonly these devices are described in terms of the number of poles and throws. Pole refers to the number of circuits a switch operates. Throw refers to the number of positions each switch pole can be connected to. Common switch forms:

Contact Form	Switch Function	Circuit Diagram
SPST – Single Pole, Single Throw	On-off
SPDT – Single Pole, Double Throw	Centre off (on off on) or Changeover switch
DPST – Double Pole, Single Throw	On-off
DPDT – Double Pole, Double Throw	Centre off (on off on) or Changeover switch

Switch Action – Latching or Momentary?

When selecting a rocker switch, you need to decide if you require a latching or momentary switch action. Latching - this means that the switch activates when pressed and the circuit is not broken until the switch is pressed again. Double pole, on-off, latching rocker switch Momentary – the switch circuit is connected when the actuator is pressed and disconnects as soon as the rocker is released. A momentary switch action is shown as follows: Single pole, momentary centre-off (on)-0ff-(0n)

Switch Ratings

Switches are rated by their electrical characteristics. Voltage and current are the two principal ratings. Current Rating - The current rating of a switch notes the maximum amount of current the switch is designed to carry. This rating is dependent on the voltage of the circuit in which the switch is used. If the maximum current is exceeded, there is a danger that the switch contacts will weld together meaning the electrical circuit will no longer open. Voltage Rating – this refers to the maximum voltage allowable in the electrical circuit where the switch is used. The voltage rating may be given as AC or DC voltage, or both. Types of load – you also need to consider the electrical load in a circuit. Load is a generic term for something that draws power. Simply put, it is the piece of equipment you turn on and off. The amount of current drawn, multiplied by the voltage equals the amount of power used by the device. Resistive loads primarily offer resistance to the flow of current. Examples of resistive loads are heaters, ovens, toasters and irons. If the device is likely to get hot and doesn’t move, then it is most likely a resistive load. Inductive loads are generally devices that move and usually include an electric magnet, like an electric motor. Examples of inductive loads include power drills, mixers, fans, sewing machines and vacuum cleaners. Transformers also produce inductive loads. High inrush loads draw a higher amount of current or amperage when first turned on compared to the amount of current required to continue running. The initial surge in current can cause switch contacts to weld together. This additional demand on a switch must be considered for applications such as Motors which often have high inrush loads.

Rocker Switch Sizes

The size of a rocker switch is generally referred to as “cut-out”. Rocker switches usually snap fit into a panel on an application. The cut-out is the size of the hole which the switch will fit into. Rocker switch shapes are commonly round or rectangular. We supply a whole range of rocker switch sizes to suit the majority of applications: ABSL series – 19x6.8mm slim line small rocker switch A1 series – 19x13mm A4 series – 22x19mm B1 & SX81 series – 30x11mm B4 & SX82 series – 30x22mm ABRR series – 20mm round rocker switches Above is an example of the cut out information provided on a typical data sheet.

Switch colour, illumination and marking

The majority of rocker switches are black or white, however, they can be supplied in a variety of colours. Most illuminated switches are red, green, amber or blue and again, other options are available particularly if using an LED lamp. Our illuminated versions are available in 12VDC or 24VDC as well as mains voltage. Markings help to show the user what position the switch is in. Standard markings such as below are widely available. [products skus="TECNO11131191000,A11131121000,ABRR003,B115C11290000"] In addition, customised markings are also available however, please be aware that additional costs and minimum order quantities will apply.

IP65 Rated Rocker Switches

Our B4MASK range is IP65 rated. These switches are fitted with a rubber skirt/seal which protects the internal mechanisms from water ingress. Suitable applications include pressure washers, steam cleaners, outdoor equipment, industrial machines and control panels.

Rocker Switch Accessories

Fitting a splash proof cap to a rocker switch increases the IP rating. Standard switches are generally rated at IP40 and when a cap is fitted correctly, the rating reaches IP65.  Following is a link to our switch accessories page on our website – https://www.abcomponents.co.uk/product-category/switches/switch-accessories/
