Some common switches are shown on this information sheet. Basically switches bring contacts together in different ways but they do the same switching job.
Typical Switch Symbols
KEY SWITCH
	This switch is available in different forms. They provide limited security as a key is required to ‘switch’ them on and off.

PUSH SWITCH   These can be ‘push to make’ (push the switch to allow the circuit to work) or ‘push to break’ (push the switch to turn off the circuit). ROCKER SWITCH   This switch is common on many electrical devices. For example they are found on computer units for turning them on and off.
