The COB-61A Push-Button Switch is part of CNC Electric’s COB Series, designed for remote control of cranes, hoists, and industrial machinery. It features two mechanical buttons (typically UP/DOWN) with built-in interlock to prevent simultaneous activation.
Rated for circuits up to AC380V or DC250V at 50/60Hz, it offers overload protection, short-circuit protection, and control functionality. The IP65-rated enclosure made of shockproof ABS resin ensures durability in snowy, dusty, and humid conditions. Terminals are M4 screw type, and the unit supports AC220V and AC440V operation.
