    • An electric oven toaster construction wherein a unique cam follower and rotatable cam accurately sets the threshold temperature of a thermostat switch. The rotatable cam includes relatively steep rise surfaces and the cam follower includes a generally flat mounting portion, a short blade portion and a slide portion in contact with the rotatable cam. An adjusting screw is threaded through the short blade portion close to the mounting portion. With this construction, the rotary position of the cam may be manually adjusted to accurately move the short blade portion and the adjusting screw to accurately move a thermostat switch contact only approximately one-third of the distance that the steep cam surfaces move the cam follower to accurately set the position of the thermostat switch contact to set the threshold temperature of the oven toaster.
    • 一种电烤箱烤面包机结构,其中独特的凸轮从动件和可旋转凸轮精确地设定恒温器开关的阈值温度。 可旋转凸轮包括相对陡峭的上升表面,并且凸轮从动件包括大致平坦的安装部分,短叶片部分和与可旋转凸轮接触的滑动部分。 调节螺钉穿过靠近安装部分的短叶片部分。 通过这种结构,可以手动地调节凸轮的旋转位置以精确地移动短刀片部分和调节螺钉,以便将陡峭的凸轮表面将凸轮从动件移动的距离的大约三分之一精确地移动到恒温器开关触点 准确设定恒温开关触点的位置,设定烤箱烤面包机的阈值温度。
