AN ELONGATE SWITCH FOR USE IN AN ALARM SYSTEM

摘要

A switch comprises an elongate hollow body (32), an elongate light source (48) and an elongate channel (30). The elongate hollow body (32) is resiliently deformable and comprises first and second electrical contact strips arranged so that the contact strips are brought into contact to close the switch when the hollow body (30) is deformed. The elongate light source (48) is coupled to the elongate body (32) along at least part of its length and arranged to illuminate at least part of the switch. The elongate channel (30) is arranged to support the hollow body (32) and the light source (48) such that the channel (30) partially surrounds the hollow body (32) leaving a portion of the hollow body (32) exposed within an open part of the channel (30) allowing the hollow body (32) to be deformed within the channel (30).
