The switching unit has spring arms 69a which are a push fit on to lugs 40L on the body of the actuating unit. Similar lugs 62L on the switching unit allow the addition of further similar units for conjoint actuation. The switching unit comprises a resiliently mounted bridging contact on a sliding rod 67 which is moved by a rod 51 protruding from the actuating unit. The latter comprises a moulded platics housing 20 and an end cap 40.

A transparent push-button 23 is retained in the housing by lugs 23t on resilient arms 23<SP>1</SP> and acts on arms 31 of an actuating member 30. A projecting finger 34 of the member 30 cooperates with another member 50 and two hair springs 53, 54 (Fig. 4, not shown) to provide push-on push-off operation of the switching unit. Fig. 11a shows the parts in the contacts closed position. Spring 54<SP>1</SP> has an extension which bears on spring 53<SP>1</SP> defining a minimum spacing: spring 53<SP>1</SP> is stronger and pushes spring 54<SP>1</SP> to the right as shown.

On release of the push-button, finger 34 is withdrawn and spring 54 allowed to move further to the left. A second depression causes finger 34 to push spring 54<SP>1</SP> to the left, the extension thereon pushing spring 53 off the projection 52s to release the contacts to the closed position.
