The APEM Panel Switches S-SR are double pole autoswitches with paddle actuators, featuring silver or gold-plated contacts. These switches offer high dielectric strength (1,000 Vrms 50 Hz min.), low initial contact resistance (10 mΩ max.), and robust environmental performance including -40 °C to +85 °C storage and -20 °C to +85 °C operating temperatures. Ideal for industrial applications requiring reliable switching in harsh conditions.

Product Overview

The APEM Panel Switches S-SR are double pole autoswitches designed for demanding industrial environments. These switches utilize silver or gold-plated contacts to ensure reliable electrical performance with low initial contact resistance (10 mΩ max.) and high dielectric strength (1,000 Vrms 50 Hz min.). The robust construction, including a complete seal that withstands 56 days of moisture testing (IEC 68-2-3), ensures long-term reliability in both wet and dry conditions across a wide temperature range from -40 °C to +85 °C for storage and -20 °C to +85 °C for operation. Their wave solderable and washable design makes them suitable for automated manufacturing processes while maintaining process compatibility.

Electrical Performance

The S-SR switches deliver reliable electrical performance with a maximum current rating of 4 A at 30 VDC for silver contacts (A or 1) and 0.4 A at 20 VAC or DC for brass, gold-plated contacts (CD or 0). Silver, gold-plated contacts (AD or 2) support 4 A at 30 VDC (300 mA at 30 VDC for gold plating). The switches maintain low initial contact resistance (10 mΩ max.) and high insulation resistance (1,000 MΩ min.), ensuring minimal power loss and excellent electrical isolation.

Environmental Resilience

Engineered for extreme conditions, the S-SR switches operate across a wide temperature range from -20 °C to +85 °C and can withstand storage temperatures as low as -40 °C to +85 °C. The complete seal and insulating materials ensure the switches pass a 56-day moisture test (IEC 68-2-3), making them suitable for use in humid or wet environments without degradation.

Construction and Process Compatibility

The switches feature a wave solderable and washable design, allowing seamless integration into automated manufacturing processes. This construction ensures durability without compromising on the switch's ability to withstand cleaning cycles and soldering operations, critical for high-volume production environments.

Optional ESD Protection

ESD protection is available as an optional feature, providing additional safeguard against electrostatic discharge in sensitive electronic environments. This feature enhances the switch's reliability in applications where static electricity could cause damage to connected components.
