Switches

Toggle Switches


These switches are used in simple applications say two modes and are used mostly in machines were we need a constant switching between two modes.

Selector Switches:

These switches surf between a large number of modes, a simple example of selector switch is a type of ordinary electric fan regulator switch which switches between a wide range.

Drum Switches:

These switches commonly are power supply switches,since they are mostly used to switch ON lathes and drilling machines.They are also used to switch motors to run at forward or in reverse direction.

Rotary Switches:

They perform switching operation throughout 360 degrees example a type of ordinary electric fan regulator switch which rotate 360 degrees.

Limit Switches:

These switches are used to protect a machine part from exceeding its axial distance in case if the part runs off the limit the switch reverses the direction of the part by reversing the direction of rotation of the prime mover mostly a motor.It is actuated by machine part touching it's lever.

Push Button Switches:

These switches are used to control a function either switching 'on' or 'off'.They are mostly used in conventional lathes.

Membrane switches

These switches are of typical use they are used in the contol panel of CNC machines to denote the alpha numeric characters they give a membrane coating to the buttons(switches).
