These terrific lever-actuated microswitches from Omron are the industry standard for paintball markers. Some circuit boards Omron switches by default, but some use asian import switches which are decidely inferior. Omron switches offer the best click and return consistency.
Omron trigger microswitches are available in 25 gram or 80 gram. The two switch weights are used by various marker developers, depending on their trigger design and electronic settings. The 80-g switches provide a more "clicky" feel and can also help to control bounce; the 25-g switches allow for a lighter pull.

Top-actuated switches are primarilly found in markers where the switch is attached to a wire pigtail. Be sure to use heatshrink to insulate your bare wire connections when soldering. These are also used with some markers that position their microswitches above the trigger. Top-actuated switches are used in the following markers:

· Smart Parts Shocker SFT, Shocker NXT, and Nerve · Smart Parts classic Impulse · Smart Parts Shocker Sport (LS board) · Smart Parts Ion · non-Alias Bob Long Intimidator · AKALMP Viking and Excalibur · Dye DM4, DM5, and DMC (non-UL frame) · Proto Rail (non-UL frame)

· Diablo Wrath · Toxic Toys Tribal · ICD Bushmaster · Brass Eagle Rainmaker · SystemX Alien & NME · Empire Axe & Vanquish (shorten the terminals before soldering) · Eclipse Etek 2, Etek 3 · Others

Side-actuated switches are used in markers that mount their board parallel with the frame. These switches are used in the following markers:

Left-facing microswitch: · FEP Quest · MacDev Cyborg · DLX Luxe · Smart Parts 09 Impulse · ICD Freestyle · Dye DM3 (including Gen-E) · Proto SLG · Bob Long Marq · Tadao Ebisu board for Bob Long G6R · Vaporworks board for Bob Long Alias Intimidator · Tadao Ego 05 board · WDP/APS Angel (LCD & LED stock board) · Predator "FRM board" for Angel LCD · Virtue boards for Dangerous Power Fusion (with bent lever) · Action Markers Diadem · Regency Crome2 · Others

Right-facing microswitch: · Eclipse Etek 1 · Eclipse Ego · Bob Long G6R (stock, Virtue) · Bob Long Alias Intimidator (stock, Tadao, Predator, Virtue) · Dye Ultralite frame boards · Dangerous Power Fusion (E1, APE) · Dangerous power FX · Virtue board for Eclipse Ego 05+ · Angel Mojo board · Tadao board for Eclipse Ego 06+ · Machine Vapor · J4 Torque · Vanguard Creed ARV · many aftermarket boards for Angels (Virtue, Tadao, Predator FRM, Lucky) · Others

This button is used on many paintball electronics, including the following:
· Shocker/Nerve stock upper and lower boards
· Many Shocker aftermarket lower boards
· Smart Parts and some aftermarket Ion boards
· E/X-Mag boards
· Note: this switch doesn't work on older Ion T-boards (revision-A, B, and C) or revision-B Virtue Ion boards.
This switch is slightly different than the one used by Smart Parts. The difference is that this button doesn't have the "raised" lip; this helps make the button pad more difficult to break off.

Same as above, except bulk pricing on multiple switches. This can be useful if you're repairing team markers, or if you just want some extras for future use!

Replacement power switch (button) on Halo, Reloader-B, and Draxxus Pulse boards. This button will work on all boards except the really old stock ones from 2002. Fits the following:
· Halo Z-code boards
· Halo Victory/V35 boards
· Predator Cheetah board
· Angry Halo boards
· Reloader-B boards
· newer "LE" boards (2003 and later)
· Draxxus Pulse mainboard

This switch attaches to the front of the circuit board and controls the fire mode on LS Turbo boards and DS S/F boards. This switch can be used to convert any DS 4x4 board into an S/F just by installing the switch in position. It can also be used to repair a damaged switch of the same type.
Please note, the white fire mode switch that was originally used on Shocker boards has actually been discontinued. I'm selling this red replacement which can be used as a substitute. However, the switches are slightly different so you must be sure to position it correctly on the board. If you solder it in the wrong position, you can drill the switch hole wider to allow a better fit.

These buttons are used on many paintball marker circuit boards at the rear of the frame, for operation and programming. If your current switch breaks, you can remove and replace it with one of these. The following markers use this model switch:
· Dye ultralite frame boards
· Proto SLG
· Eclipse E-blade
· Eclipse Ego
· Eclipse Etek 1
· FEP Quest
· Cyborg (with a button extender)
· most universal Angel boards
· others
