Material: Hard Rubber and metal
Manufacturing Process: Molder
Function: When engaged, pushes down on pin to open water flow in spray gun.
Trigger is engaged by the user. Red component of trigger can be used to lock to trigger to the engaged setting.
Hard Rubber used because it is durable yet easy on the hands.
Force Perpendicular to trigger surface is applied to trigger.
Magnitude is estimated at 2 lbs.
The material choice does effect the process. If it were metal instead of a rubber it might have been cast instead, and that might have cost more money.
Each manufacturing process was chosen for this component because it was the easiest, fastest, and cheapest way to do it at high volumes of product.
The trigger has a particular shape to form to someone's hand and make easy to use the trigger.
The component is both functional and cosmetic. It performs its task yet its color matches the rest on the power washer to make it look appealing to the eye.
This processes were chosen because they were the most cost effective way to make the part.
On a scale from 1-5, 1 being the simple like a ball, and 5 being complex like a engine, this component is a 1. This component is very basic. Its simple job is to supply a surface where a force to activate the trigger switch could be applied.
