• Compliant to all relevant British safety standards. Minimum mounting depth: 16mm.

• On this circuit you would need the middle switch to be intermediate (i.e. the one at the top of the stairs) in order for all the switches to function properly.
• A typical example of this is on a landing. There is a switch at the bottom of the stairs, one at top of the stairs and one at the end of the landing.
• An intermediate switch is used when you have three switches controlling one light.
