Abstract

This multicontact relay for low current and voltage service is constructed with a sealed type of elastic diaphragm switch and an actuator. The relay comprises an upper set of switches 10, a lower set of switches 11, and an actuator plate 12 between the two switch sets. Each switch set consists of a base plate bearing a set of parallel contacts, a perforated center sheet of elastomeric material and an elastic diaphragm having parallel contact lines crossing those on the base plate. Pressure on the diaphragm moves its contacts through the perforations into engagement with the contacts on the base. Plate 12 between the two switch sets is formed with switch actuating parts for each switch contact which is to be controlled. Plate 12 is connected by link 13 to armature 14, pivoted on shaft 15.

Multicontact Relay

This multicontact relay for low current and voltage service is constructed with a sealed type of elastic diaphragm switch and an actuator. The relay comprises an upper set of switches 10, a lower set of switches 11, and an actuator plate 12 between the two switch sets. Each switch set consists of a base plate bearing a set of parallel contacts, a perforated center sheet of elastomeric material and an elastic diaphragm having parallel contact lines crossing those on the base plate. Pressure on the diaphragm moves its contacts through the perforations into engagement with the contacts on the base. Plate 12 between the two switch sets is formed with switch actuating parts for each switch contact which is to be controlled. Plate 12 is connected by link 13 to armature 14, pivoted on shaft 15. Armature 14 is biased counterclockwise by spring 16 and is driven clockwise by energization of coil 17. Spring 16 normally holds armature 14 so that plate 12 is pressed downwardly against switch set 11 to make selected circuits in it. When coil 17 is energized, plate 12 is moved upwardly to open the lower switches and make the selected switches in upper switch set 10.
