Custom Kroll Switch Upgrade for Pelican M1/M3/M6 Incandescent (pre-2014 only)

Description

Up for listing: custom brass Kroll switch assy (sleeve with switch installed) for use with Pelican M1(3310)/M3(3370)/M6(2320/2390) tailcap hosts manufactured before 2014 (dubbed "Type A" assy)
Inspired by original Sandwich Shoppe aluminum sleeve design (also compatible with pre-2014 batches only)
Kroll switch preinstalled and preadjusted
Low in stock -- may be discontinued once sold out
Highlights and features:
- Designed for Judco Kroll (1052) clicky switch mecha only (McClicky NOT compatible);
- Converts old-spec twisty tailcap to durable clicky switch design (for models equipped with twisty tailcap);
- Replaces stock silent clicky switch mecha for a more robust and reliable clicky switch operation (for models equipped with stock silent clicky tailcap).  User serviceability via use of commercially available Kroll clicky which allows for easy replacement (stock clicky mecha CANNOT be replaced once defective);
- Makes use of full internal tailcap host threads for secure installation;
- Retains similar amount of tailcap threads (as compared with stock spec) for latching (screwing) into body's tail threads; only slight increase in body/tail gap length (no more than 3mm total)
- Sleeve height (overall) ~17mm;
- Supports switch lockout function (only if tailcap host is reanodized inside-out with internal threads fully covered, at customer's expense)
NOTE: some advanced skills required for those having pre-2014 clicky tailcaps
Disassembly instructions:
1. Using needle nose pliers, unscrew black plastic receiver and remove contents (contact spring + pin, main clicky mecha with soldered PCB);
2. Moist and clean threads and affected areas with industrial-grade solvent (pref. acetone-based) to weaken/dissolve glue, then use cotton swabs and/or pick/hook to carefully scrape out residue;
3. Once tailcap host is dry (no wet solvent) and threads are free of aforementioned glue residue, wiggle and spin out brass disc by wedging center hole with finger or flat nose pliers with reverse-taped (ie. adhesive facing outside) tips.  Brass disc itself should be only weakly (or even not) threadlocked, is ~2mm thick, and can be effectively removed using the nose plier method;
4. (Optional) Carefully drill two small torque holes on brass disc to assist removal/reinstallation using needle nose pliers.  If (3) fails then drilling will have to done within tailcap host to initiate disc removal.  If so, do it carefully to avoid over-drilling resulting in underside component damage;
5. Remove remaining components: spring, aluminum (or plastic) boot void fill, inner aluminum collar ring (use aforementioned nose plier method to assist removal), switch boot
6. Reclean and relubricate tail host's inside threads.  Reinstall switch boot;
7. Using needle nose pliers, screw assembled Kroll switch module into tail host till snug

NOTE:
a. Use of heat gun highly suggested as moderate-strength thread glue may have been used through chassis;
b. Brown plastic washer piece may need to be broken and/or extracted with special pliers/tweezers in order to access inner brass components for effective chassis disassembly
Tailcap host compatibility:
- M6/M3/M1 clicky tailcap hosts manufactured before 2014 which feature full internal threads (Type-B setup also compatible when installed in conjunction with original aluminum collar ring from disassembled stock clicky chassis);
- Early-spec M6 twisty tailcap host which features full internal threads;
- Absolutely NOT compatible with tailcap hosts manufactured after 2014 (esp. those with embossed battery position indicator).  Use the Type-B switch upgrade instead;
- May NOT be compatible with some native LED models.  Check tailcap specs before proceeding
NOTE: If you plan to upgrade a stock clicky tailcap, please consider choosing the Type-B switch assy instead of this Type-A assy, due to the latter's limited availability which needs to be reserved for customers who need to upgrade a native twisty tailcap
