Snaptron’s S-Series domes are standard four-leg metal dome switches with two solderable tabs. The tabs allow the dome to be soldered directly to a printed circuit board or flex circuit.
Traditionally, metal domes are attached to the circuit board with adhesive tape or placed into spacer pockets. This process is typically done semi-automatically or manually and requires an assembler. With the solder dome, you can automate this process with pick-n-place or Surface-Mount Technology (SMT) equipment.
- Easily integrate SMD domes into your existing SMT system
- Reduce overall build time and eliminate steps to final product assembly
- Improve placement accuracy due to the elimination of manual methods
