Product Range
Compact Switches for Electronic Assemblies
The SMTS range covers compact lever-operated switches for panel and PCB assemblies. Compare the switching function, contact arrangement and terminal style for the exact part number. A similar appearance does not mean that two models have the same circuit or mounting footprint.
Single-Pole Functions
SMTS-101 provides ON-OFF control with two solder terminals. SMTS-102 provides SPDT ON-ON switching with three terminals, while SMTS-103-2A1 adds an OFF position between the two ON positions.
Double-Pole Functions
SMTS-202 provides DPDT ON-ON switching with six terminals. SMTS-203-2A1 provides DPDT ON-OFF-ON switching. Check the circuit diagram when your assembly needs two circuits operated by one lever.
Solder & PCB Terminals
SMTS-102 and SMTS-202 product pages list solder-terminal models and A2 PCB versions. The SMTS-102-2C3 is a three-pin PC-H terminal model. Confirm the terminal direction, pin spacing, bushing and panel clearance against the drawing.
Electrical Ratings & Accessories
The published SMTS-101 and SMTS-202 specifications list 3A at 125VAC and 1.5A at 250VAC. These are model-specific AC switching ratings, not a universal DC rating. For DC or inductive loads, send the operating voltage, current and load type for confirmation.
Toggle switch covers are shown as related accessories. The WPC page lists MTS and KN fitments; compatibility with an SMTS switch and the required sealing performance need separate confirmation.
Supply & OEM Enquiries
Send the full model code, terminal version and quantity for a quotation. OEM/ODM enquiries can include a drawing, circuit function and assembly requirements. Sample availability, packaging, minimum order quantity, lead time and any required certification documents should be confirmed for the quoted part.
Applications
Typical Switch Applications
Compact toggle switches give operators a direct control point on electronic equipment. The circuit function, mounting space and load requirements determine the appropriate model.
Instrumentation & Test Equipment
Provide manual ON-OFF or function switching on compact instrument panels and electronic test assemblies.
Communication Equipment
Use single-pole or double-pole switching for control functions in telecommunications and networking equipment.
OEM Electronic Assemblies
Match solder or PCB terminals to the assembly layout, with the circuit function and mounting drawing agreed before production.
Common Questions
Toggle Switch FAQs
Answers about switching functions, terminals, ratings and production enquiries.
For a Project Enquiry
Send a model code and quantity, or share the circuit function and mounting drawing.
Send Project DetailsThe listed models cover ON-OFF, ON-ON and ON-OFF-ON functions. SMTS-101 has two terminals; the SMTS-102 and SMTS-103-2A1 models are single-pole switches, and SMTS-202 and SMTS-203-2A1 are double-pole models. Check the exact circuit diagram before ordering.
The termination determines how the switch connects to your assembly. SMTS-102 and SMTS-202 pages list solder-terminal and A2 PCB versions. PC-H versions have a different terminal arrangement. Compare the drawing, pin spacing and mounting clearance rather than choosing by appearance alone.
A published AC rating does not establish a DC switching rating. Tell us the operating voltage, current and load type so the required model can be checked. Do not use the dielectric test voltage or insulation-resistance test voltage as an operating rating.
Do not assume a range-wide IP rating or approval. Cover compatibility and sealing performance must be checked for the exact assembly. If your project requires an IP rating or certification, include that requirement and request the applicable model documentation before ordering.
Send the model code, switching function, terminal version and quantity. For an OEM enquiry, add the mounting drawing, electrical load and any packaging or compliance requirements. Sample availability, minimum order quantity and delivery timing will be confirmed with the quotation.
Request a Toggle Switch Quote
Send the model code, terminal version and quantity. For a new assembly, include the switching function, electrical load and mounting drawing so we can review a catalog model or an OEM requirement.
