Pilot lights and illuminated switches are suitable for direct supply with series resistor with diode, using bayonet cap filament bulb type BA9S as follows:

Supply voltage for direct connection without series resistor: 6V – 130V

Supply voltage through series resistor: 12V – 230V

Supply voltage through series resistor and diode: 230V (Bulb-130V)

Simple to fix – screw driver is all that is required, Fixing method unaffected by excessive vibration-unit does not rotate

Safe, very good flame resistance

Shrouded terminals, protection against electrical shock (unit earthed)

Circular actuators have chrome plated metal bezels or double insulated plastic bezels

Contact Elements are double break and have self-wiping contacts. The elements are interchangeable and can be stacked without additional hardware.

1 to 6 elements (NO or NC) can be used with pushbuttons and selector switches.

1 or 2 elements (NO or NC) can be used for illuminated switches
