SPST 2-Position 1021 Industrial Heavy-Duty Toggle Switch – 2-Terminal,
The 1021 Toggle Switch is a highly reliable, high-capacity industrial panel switch designed for straightforward, single-line circuit connection and power isolation. Featuring a rugged, high-leverage metal bat lever handle, this switch provides crisp mechanical engagement and distinct manual positioning. It operates via a 2-position maintained mechanism (ON-OFF), acting as a primary gatekeeper to safely supply power to a machine or completely cut off the circuit. Configured with 2 robust screw terminals forming a Single Pole Single Throw (SPST) layout, it delivers outstanding electrical continuity, high thermal stability, and an extended service life across factory machinery, control panels, test equipment, and automotive installations.
