Key Switch Heads

A selector switch or key switch head is an important component of a selector switch, which is required when more than one control option is needed. Switch heads can come in a variety of forms, and are usually made from a hard material, such as plastic or metal.

What different types of switch heads are available?

Switches can come in a variety of styles and colours, and can be illuminated or non-illuminated, depending on the required application.

Key operated switch - A switch may have a key position selector, to increase security in industrial environments where the user is operating dangerous equipment, and a circuit breaker may be required.

Selector switch - The device may have a rotary selector, with the number of positions available ranging from two to four.
