<p>An interlock arrangement for two slide switches for a radio pager ensures that incorrect switch operation does not occur.</p><p>The casing has two switches (A and B) with respective switch members (15,16) inside the casing. Switch member A has a cam follower (15b) on an arm which can co-operate with one or other of two indents (13, 14) and switch B has a chamfered end (16a). The chamfer and the cam follower are so shaped that when A is in position 1, the other switch member locks A, while if A is operated first attempted movement of B locks A in its new position.</p> |
