3-hole high-resistance thermoplastic control station enclosures are typically used for on-site control equipment requiring multiple pushbuttons, indicators, or selector switches. Thermoplastics offer distinct advantages in weight, machinability, and media resistance; however, specific thermal, chemical, and mechanical properties depend on the material grade and product specifications.

Key design considerations include hole diameter, spacing, arrangement, component types, panel thickness, cover construction, mounting style, and cable entries. Modifying hole counts or button layouts requires evaluating tooling, structural impact, and order volume. This article covers key material, cutout, and mounting considerations for 3-hole enclosures.
