Switches — buying guide & FAQs
A switch makes or breaks a circuit, and the right one comes down to the action, the electrical rating and the actuator that suits the job. We stock the full range of electromechanical switches, with particular own-brand depth in push-button and rocker.
What types of switch are there?
How do I choose a switch?
- Rating — match the current and voltage to the circuit it switches.
- Action — momentary (on while pressed) or latching (stays put).
- Configuration — SPST, SPDT or DPDT for how many circuits it controls.
- Actuator and mounting — button, rocker, toggle or rotary; panel or PCB mount.
- Extras — illumination, or a waterproof rating for harsh environments.

Switches — frequently asked questions
What is the difference between a momentary and a latching switch?
A momentary switch is only on while you press it, then springs back — like a doorbell or reset button. A latching switch stays in position until you switch it again, like a light switch. Push-buttons come in both types.
What do SPST, SPDT and DPDT mean?
They describe a switch's poles and throws. SPST is a simple on/off; SPDT switches one circuit between two outputs; DPDT switches two circuits at once between two outputs. More poles let one switch control more circuits together.
What is a microswitch?
A microswitch is a small, precise snap-action switch operated by a light force, often through a lever or roller. It is used for position sensing, limit detection and safety interlocks, and typically has NO and NC contacts.
What is the difference between a rocker and a toggle switch?
Both turn a circuit on and off; the difference is the actuator. A rocker pivots like a see-saw and sits flush in a panel, while a toggle has a projecting lever you flick. Choice is down to panel style, feel and space.
How do I choose a switch?
Match the current and voltage rating to the circuit, choose the action (momentary or latching) and configuration (SPST, SPDT, DPDT), then the actuator type and mounting. Add illumination or a waterproof rating if the application needs it.
