Potter RSW-21 (GRAY) Roller Ball Switch, Gray

Ideal for precise intrusion detection and equipment position monitoring, the Potter RSW-21 roller ball switch provides dependable, wear-resistant actuation for security and surveillance systems. From access control panels to conveyor monitoring and alarm inputs, the RSW-21 by Potter Electric Signal is built to deliver consistent performance. The hardened stainless steel 5/8" roller resists deformation and wear, while a controlled 3mm operating stroke ensures fast, repeatable switching with minimal travel—critical for accurate monitoring and tamper detection. Designed for recessed mounting in a 3/4" drilled hole, the compact gray housing installs cleanly in panels and enclosures. Choose SPST or SPDT contact configurations for maximum wiring flexibility; the switch is rated for up to 200V DC and includes #22, 25" lead wires for straightforward field connections. With a modest operating force and robust construction, the RSW-21 reduces maintenance and downtime in commercial security, surveillance, and industrial monitoring applications.
