Switches - Mechanical

Mechanical Switches

Mechanical switches are one of the most common electrical devices as they allow power to be turned on or off.

Switches are rated for the amount of current and voltage they are suitable for. For switching low power and low currents like using a switch as an input to a microcontroller just about any switch will do. When using a switch to control power from a battery or turn a motor on then care should be taken to ensure the switch is rated to the expected current. For high power uses an electronic solid state switch can be better.

Mechanically switches are varied. Momentary switches are either on or off while you hold them like buttons while others will maintain the state until switched back like toggles or sliders. Like relays, switches can be SPST (single pole single throw), DPDT (double pole double throw) or lots of other variations.

 

Rocker Switch: 3-Pin, SPDT, 10A

Code: SKU-002572

This single-pole, double-throw (SPDT) rocker switch makes a great on/off power switch. It is rated for 10 A at 125 VAC and 6 A at 250 VAC.

Rotary Switch - 10 Position

Code: SKU-002105

This is a single pole, 10 position rotary switch able to select up to 10 different states in a durable package. Unlike our other rotary switch, this model is much more robust and capable of handling larger currents and voltages.

Tactile Button - SMD (12mm)

Code: SKU-001941

This is an SMD 12mm square SPST button. What we really like is the large button head and good tactile feel (it ‘clicks’ really well).

Tactile Button - SMD (6mm)

Code: SKU-001940

This is an SMD 6mm square SPST button. What we really like is the little button head and good tactile feel (it ‘clicks’ really well). This button is great for user input or a good reset button on a PCB.

Thumb Joystick

Code: SKU-000301

This is a joystick very similar to the ‘analogue’ joysticks on PS2 (PlayStation 2) controllers. Directional movements are simply two potentiometers - one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is pressed down.
