MT series

Product catalog summary

Overview: The MT series sealed selector switches by APEM are designed for environmentally challenging conditions, offering IP68 sealing. They are versatile with multiple functions and contact materials suitable for various applications, from dry circuits to 4A loads.

Electrical and General Specifications:

Current/Voltage Rating: Silver contacts support 4A at 30VDC, while gold-plated silver contacts also support 4A at 30VDC but can handle up to 100mA at 30VDC. Gold-plated brass contacts are rated at 0.4VA for 20VAC or DC.
Minimal Load: Silver contacts require a minimum of 50mA at 10VDC, whereas gold-plated contacts require 10mA at 50mV or 10µA at 5V.
Contact Resistance: Initial contact resistance is a maximum of 10mΩ.
Insulation Resistance: Minimum of 1,000 MΩ at 500VDC.
Dielectric Strength: 1,000 Vrms at 50Hz between terminals and 1,500 Vrms at 50Hz between terminals and frame.
Contact Bounce: Maximum of 2ms.
Electrical Life: 50,000 cycles at full load, with a mechanical life of 100,000 cycles.
Panel Thickness: Maximum of 11.5 mm.
Operating Temperature: Ranges from -40°C to +85°C.

Materials:

Actuator: Made from 6/6 nylon with a soft touch thermoplastic elastomer overlay.
Bushing: Chrome-plated brass.
Contacts: Available in silver, gold-plated silver, and gold-plated brass.
Terminal Seal: Epoxy sealed.

Mounting and Packaging: Standard hardware includes a hex nut and sealing gasket. Packaged in units of 40 pieces per tray.

Panel Cut-Out: Dimensions are provided in both millimeters and inches, with a cut-out diameter of 17.65 mm.

Actuator Options: Available in rocker, winged, and paddle styles, with options for soft touch finishes.

Electrical Functions: Various configurations include ON-ON, ON-OFF-ON, MOM-OFF-MOM, ON-OFF-MOM, and ON-MOM.

Contact Materials and Finishes: Options include silver, gold-plated silver, and gold-plated brass, with bushing finishes in bright chrome or matte black.
