PCB Processing

Soldering:

Wave Soldering recommended. See Profile A in Supplement section.

Manual Soldering: See Profile A in Supplement section.

Cleaning:

Automated cleaning. See Cleaning specifications in Supplement section.

Switches should not be operated or have any pressure on the actuators during cleaning.

Full face illuminated models suitable only for bottom board spray wash to avoid contamination

of the 2-layered actuator, which may compromise the aesthetics.

Standards & Certifications

The JF Series tactiles have not been tested for UL recognition or CSA certification.

These switches are designed for use in a low-voltage, low-current, logic-level circuit.

When used as intended in a logic-level circuit, the results do not produce hazardous energy.
