InSinkErator STS-SO Air Switch Satin
InSinkErator STS-SO Air Switch Satin
Description
The InSinkErator STS-SO (SinkTop Switch) is a dual-outlet air-activated control system for garbage disposals, offering a clean countertop installation without electrical switches. This professional-grade DXF template ensures precise hole placement for granite, quartz, marble, and solid surface fabrication. The air switch requires a 1.25-inch diameter hole with maximum counter thickness of 1.5 inches, making it compatible with most stone countertop applications. Fabricators rely on accurate templates to prevent costly material waste and ensure first-time-right installations.

The InSinkErator STS-SO (SinkTop Switch) is a dual-outlet air-activated control system for garbage disposals, offering a clean countertop installation without electrical switches. This professional-grade DXF template ensures precise hole placement for granite, quartz, marble, and solid surface fabrication. The air switch requires a 1.25-inch diameter hole with maximum counter thickness of 1.5 inches, making it compatible with most stone countertop applications. Fabricators rely on accurate templates to prevent costly material waste and ensure first-time-right installations.
Installation Overview
Installing the InSinkErator STS-SO requires careful attention to hole diameter specifications. The template guides CNC programming for a clean 1.25-inch diameter cutout, positioned according to customer preference typically 2-4 inches from the sink rim. During fabrication, use diamond-coated hole saws or CNC router bits suitable for the material hardness. The air switch assembly includes a rubber gasket that seats between the push button and countertop surface, creating a watertight seal when the plastic mounting nut is tightened from below. The system connects via a 6-foot air tube to the disposal-mounted control module, eliminating any electrical connections at the countertop level. This makes it ideal for wet areas where electrical switches pose safety concerns. Maximum counter thickness is 1.5 inches, which accommodates standard 2cm and 3cm slabs. The dual-outlet power module can control two separate appliances, typically a garbage disposal and a hot water dispenser.
CNC Cutting Notes
For CNC fabrication, program the tool path for a 1.25-inch finished diameter hole using appropriate feed rates for the material type. Granite and engineered quartz require slower feed rates with continuous water cooling to prevent thermal cracking. Use a spiral upcut bit for cleaner edges on the top surface, or employ a two-stage drilling approach with pilot hole followed by final diameter. Edge quality is critical since the rubber gasket sits directly on the stone surface. Any chips or irregularities will compromise the watertight seal. For manual fabrication, mark the center point precisely and use a 1.25-inch diamond hole saw with guide bit. Support the material from below to prevent breakout on the exit side.
Material Compatibility
This air switch template works with all common countertop materials including granite, marble, quartzite, engineered quartz (Caesarstone, Silestone, Cambria), solid surface (Corian, Hi-Macs), and ultra-compact surfaces (Dekton, Neolith). The 1.25-inch hole diameter provides adequate mounting stability across material densities. For thinner materials like laminate or butcher block, verify that the mounting nut has sufficient thread engagement. The rubber gasket accommodates minor surface variations, making it forgiving on honed or leathered finishes. Polished surfaces provide the best seal. When fabricating for outdoor kitchens, ensure the client understands that the air switch control module must be protected from weather exposure in an enclosed cabinet.
Where to Buy
InSinkErator STS-SO air switches are available through major plumbing distributors including Ferguson, HD Supply, and local kitchen and bath showrooms. Retail availability includes Home Depot, Lowe's, and Amazon. Fabricators can purchase in bulk through wholesale plumbing suppliers. The kit includes the countertop push button assembly (available in chrome, white, satin nickel, and other finishes), power control module, air tube, and all necessary mounting hardware. MSRP ranges from 45-65 USD depending on finish. When quoting jobs, factor in the installation hole as a separate line item from sink cutouts.
