527 Description

Short technical summary and product information.

The APEM Inc. 527 toggle switch is part of the 5000 series, offering a sleek design and compact size suitable for various applications. This switch features a momentary-off-momentary (MOM OFF MOM) electrical function, ensuring reliable operation for lighting and machinery control.

With a bushing diameter of 11.9mm (15/32), it supports panel mounting and is compatible with PC terminals. The switch is rated for an electrical life of up to 50,000 cycles at full load for single and double pole configurations. It operates reliably within a temperature range of -40°C to +85°C.

Key specifications include a maximum initial contact resistance of 10 mΩ, minimum insulation resistance of 1 GΩ at 500VDC, and a dielectric strength of 1,000 Vrms between terminals and 1,500 Vrms between poles and terminals to frame. The maximum contact bounce is 2 ms. The switch can accommodate panel thicknesses of 2.5mm with two nuts or 4mm with one nut, and has a maximum applied torque of 1.25 Nm to the nut. It also boasts a mechanical life of 100,000 cycles.

UL and CSA approved, the APEM 527 toggle switch is a robust component for demanding environments.
