ZHUCO SC-68/2GS 0-1 Two-Pitch Two-Section Power Switch (Double Pole Four Groups in Parallel)

The SC-68/2GS is a 20A rated current dual-position (0-OFF, 1-ON) rotary power switch. It employs a double-section (two-layer) structure, with each layer containing two sets of independent contacts in parallel, providing a total of four sets of synchronously connected and disconnecting contacts (1-2, 3-4, 5-6, 7-8). This ensures stable, low-impedance connection and safe disconnection in switching currents or main circuits requiring higher safety.

Rated operating current: 20A
Rated operating voltage: ≤ 600V AC
Rated insulation voltage: 690V
Power frequency: 50Hz ~ 60Hz
Contact configuration and function:
Position “1” (ON): All four sets of contacts (1-2, 3-4, 5-6, 7-8) are simultaneously connected.

Position “0” (OFF): All contacts are simultaneously disconnected, providing a clear electrical isolation point.

Contacts: Constructed of silver alloy or equivalent high-performance materials to ensure low contact resistance, good conductivity, and arc resistance.

Insulation and Housing: Made of flame-retardant, high-temperature resistant engineering plastics, meeting high insulation voltage (690V) requirements and possessing high mechanical strength.

Design: Compact structure, moderate operating torque, clear positions, and good contact synchronization.

Designed to comply with relevant electrical safety standards; high insulation voltage provides safety for personnel.

Application Scenarios: This switch is specifically designed for applications requiring reliable switching of small to medium power supply circuits or as a main switch for equipment. Its multi-contact parallel structure enhances connection reliability.

Main Power Switch: Serves as the main power input switch for small to medium-sized industrial equipment, testing instruments, power cabinets, or control boxes, providing reliable connection and safe isolation functions.

Load Control and Isolation: Used to directly control the start and stop of single-phase or three-phase loads (such as motors, heaters, and lighting circuits) with a rated current of up to 20A, and can also serve as a physical isolation point during maintenance.

Circuits requiring high connection reliability: In applications where high connection reliability is critical, the four-contact parallel design effectively reduces the risk of contact failure and is suitable for vibration environments or critical power supply paths.

General power distribution and control: Widely used in power distribution and control circuits in industrial automation, power electronics, and laboratory equipment as manually operated switching components.
