Abstract
Abstract A portable latching switch which has a switch body containing three cavities. An elongated cavity extends into the switch body for receiving an actuating member. The second and third cavities communicate with and extend transversely from the elongated cavity and contain latching members. An electrical switching member is responsive to movement of the latching member located in the second cavity. A locking member is contained in the third cavity whereby upon actuation of the electronic device a key is required for resetting of the latching member in the third cavity and subsequently of the actuating member.

Claim 1
Independent Claim
306 words
An improved latching switch, comprising: (a) A portable switch body having an aperture formed therein and a first elongated cavity extending into said body from said aperture for receiving a switch actuating member therein; (b) a switch actuating member positioned in said cavity and adapted for movement along a length of said cavity; (c) a biasing means positioned in said cavity for causing said actuating member to extend through said aperture and from said body; (d) a second elongated cavity formed in said body, said second cavity communicating with said first cavity and extending transversely thereto; (e) a third elongated cavity formed in said body, said third cavity communicating with said first cavity and extending transversely thereto; (f) a first latch means movably positioned in said second cavity for engaging and restraining said actuating member at a first location of said actuating member at which location said actuating member extends partly from said switch body; (g) a second latch means movably positioned in said third cavity for engaging and restraining said actuating member at a second location of said actuating member at which location said actuating member is substantially recessed within said first cavity; (h) an electrical switching means positioned in said switch body and responsive to movement of said first latch means in said second cavity for providing a first switching state when said switch actuating member is positioned at said first location and a second switching state when said switch actuating member is moved from said first location and is positioned at said second location; and, (i) a key means for engaging and actuating said second latch means for releasing said latched actuating member from its second location whereby said biasing means causes said actuating member to advance to said first location in said first cavity at which it extends partly from said body.
