Abstract

A water-tight limit switch has a connection cable 23 and a micro- switch 2 placed in a sealed metallic casing 8 with a membrane 10 transmitting the movement, from actuator 4, 5, 6 and is adjustable in position by a screw 18 which passes through the cover 16. The internal volume is part filled with a hardenable plastic mass 28 through an aperture 29 while the switch is tilted. An internal insulating casing 13 maintains an air gap about the terminal 15. <IMAGE>
